Making Essential Backups

Making a NAND Backup

Important

A NAND backup is crucial to have, it's a full backup of the internal storage of your Switch and can be used to restore the device to a working state in case of emergencies. DO NOT SKIP THIS STEP

Once the backup is finished, keep it somewhere safe. The best backup is the one you have but never need, and the worst backup is the one you need but never made. To save space, it's recommended to compress the end-result with a .zip file or something similar.

It's highly recommended that you use an microSD card that is formatted to FAT32 and has at least 32 gigabytes of space free. This will still work on smaller cards, but it's not ideal.

Instructions:

  1. Enter RCM and inject the Hekate payload.
    • If you use a modchipped Switch, you can simply just turn your Switch on with the Hekate payload renamed to payload.bin on the root of your SD.
  2. Use the touch screen to navigate to Tools and then Backup eMMC
  3. Tap on eMMC BOOT0 & BOOT1
    • This should only take a few seconds, but if your microSD card is very slow, it may take around a minute.
  4. Tap on Close to continue, then tap on eMMC RAW GPP
    • This will take a long time. Expect it to take between 10 minutes to an hour (or more, if your microSD card is very slow).
    • On FAT32 microSD cards or cards that have less than 32 gigabytes of space available, the NAND will be split into 1 or 2 gigabyte parts.
    • Hekate will stop producing these parts when it runs out of space. When this happens, do the following:
    • Power off your system.
    • Insert your microSD card into your PC.
    • Move all files from the backup folder on your microSD card to a safe location on your PC.
    • Insert your microSD card into your Switch.
    • Enter RCM again, inject Hekate again, and continue the backup by tapping on Tools > Backup eMMC > eMMC RAW GPP
    • Repeat the process until the NAND is completely dumped.
  5. Go to the top right and press Close > Home
  6. Navigate to Tools > USB tools > SD card and plug your Switch into your PC via USB.
  7. Copy the backup folder on your microSD card to a safe location on your PC.
  8. Once done, eject the UMS device safely from within your computer's operating system and return to hekate's Home menu.
